Explanation:
Star formation can be colorful.
This chromatic cosmic portrait features glowing gas and dark dust near some
recently formed stars of
NGC 3572,
a little-studied star cluster near the
Carina Nebula.
Stars from NGC 3572 are visible near the bottom of the image, while the expansive
gas cloud above is likely what remains of their formation nebula.
The
image's striking hues were created by featuring specific colors emitted by hydrogen,
oxygen, and sulfur, and
blending
them
with images recorded through broadband filters in red, green, and blue.
This nebula near NGC 3572 spans about 100
light years
and lies about 9,000 light years away
toward
the southern constellation of the Ship's Keel
(Carina).
Within a few million years the pictured gas will likely disperse, while
gravitational encounters
will likely disperse the cluster stars over about a billion years.
